No that tool can't handle more then 1 custom tune. All i have been doing is tweaking the tunes i have been sending you and over writing them on my end. Don't worry though the last tune i sent you should have all your boost back along with some better throttle response from a dig. Give a try and let me know asap. I know people want these tunes released. Once its good for the average enthusiast pic, ill write you some custom extremes for your needs.

Hey Don Saturday night just got back from testing the latest tune you sent. throttle response is not any better, and the boost still wont climb over 32-35 psi , not sure whats going on with the tunes , but boost was 40+ before. truck will pull hard, and really shifts good at wot , but it pulled harder with the 40+ boost. no bucking at all. midrange seems ok. no codes at all
i do notice transmission downshifts alot sooner under load, Not a big fan of that. I think holding the final gear and letting the
engine lug, was saving on the fuel. Just my opinion.. I do know that the "throw you back in the seat" feeling is gone in this tune.

well thats about it for me , run about 300 mile today ...... Oh by the way fuel milage on this trip was 15.5.. little petal stoming

going on though. let me know..................

Don,

Still testing the Economy tune. City driving mileage is horrible. Got 11.8 driving in town. Highway seems to be anywhere from 14.5 to 17.5, but I'm relying on the onboard computer at this point. Haven't filled up yet and I'm not driving for a few days. Will fill up again on Tuesday for the true highway number.

I'm with Pic on going back to the Extreme tune that throws you back into your seat. I was getting a consistent 12.5 around town and probably 13.5 to 14 on the highway.

Pic thats strange about the boost, the only table i touched related to boost i switched back to what i had it at before. There is no reason boost isn't climbing as high as it did before. Before loading up a new custom tune, attach the tool to ds down loader and go to options>erase custom tune. Wipe the previous one then download the new one. Maybe its just not over writing one of a similar name? It should be its just a thought. The only things i have messed with is fueling and timing. Other then that shifting, etc should all be the same.

I hate to be rehash things here but.... I have been out of the loop and would rather not read sixteen pages. Where are we and how are we?

Don,
Hoondog here with an update. Ran the truck on three day weekend. Here are my results;
economy tune 17.0mpg
original tune 16.7mpg
tow tune 16.5mpg
extreme tune 15.8mpg
These results were with 100 deg temps, dry heat, a/c on, truck unloaded with 4 people in it driving 70-72 mph. I did notice that I lost cruise control on all tunes but the original back up and the economy tune you sent me. I have the 9r10 update and assume it has something to do with the updating process??? I have to say that the economy tune is great except no bottom end (really sluggish).

awesome hoon, all the newer tunes will be a bit better on the mileage, as well as the throttle reponse coming back a bit. The reason for the sluggish feeling is that the factory ramps fuel in to reduce soot. On a 6.0, you put your foot down, you get 100% fuel. On the 6.4, you put your foot down, you get 34% fuel until the rpms rise, then it ramps in slowly. The base tables don't even got to 100%! they only reach 70%. The extreme and 80hp dont ramp it anymore. The tow and the economy having the ramping reduced significantly. all have 100% as you nail it but only when its all the way to floor. The extreme and 80hp both also have beefed up mid ranges, which may hurt economy if your more then 1/2 on the pedal but itll give it a much better "I'm not afraid to merge into traffic" feel.

So those who don't want to read all 16 pages..

1. Crusie and TCC is fixed, that was my bad on the update process.
2. Mileage should be up around highway speeds, city is tough bc the trucks dont like timing around 1300rpm, they start to buck.
3. Pedal feel should be real good on extreme and 80hp, economy and tow will be better but not in the range of the 80 and extreme.
4. Hole shots should feel better since your now getting 100% fuel when you hammer it down.
5. Shifting was obviously already fixed.

Like i said, mileage is being a bitch on these trucks, pic is picking up 2mpg, NJK is picking up some too, hoon dog is seeing a smaller increase. I think its just one of those things that once your are used to the tune, you will notice the mileage increases. Most people are pedal happy at first with the new tunes since well you are getting quite a bit more torque and it is fun heh.

o and the tcm erase problem should be fixed. I am getting ready to create a test crom. NJK and pic, you guys will get this. I need to just make sure the flashing procedure works good, tcm can erase and adjustable parameters all are in order.

SCGt94 · Post by **SCGt94** » Mon Aug 03, 2009 9:10 am

pic might as well hold on and wait for the test crom, since your going to have to do all this crap anyway. When you get the crom, restore it to stock blah blah you know the drill.

pic350ford · Post by **pic350ford** » Mon Aug 03, 2009 9:36 am

Won't be til tomorrow before I can download anything as I'm up in NH with dial up service.

SCGt94 · Post by **SCGt94** » Mon Aug 03, 2009 10:01 am

no problem, really only one person needs to tell me everything works well, flashes good and that that pesky tcm erase problem is gone, then i can release the crom to everyone else

fun fun...gotta love dial up hah.

WildBill · Post by **WildBill** » Mon Aug 03, 2009 11:11 am

So just curious Don, will this new release work for those of us with '09's? I think they are the yf series. Or are you looking at a custom tune for those apps?

yup bill, i got your cal id off ford's site and it will be added. You should be good to go once you d/l 9r11 when its released.

I want to send you that test crom bill, load it up like a normal crom and make sure you can flash your truck with no problems
